How Long Does a Furnace Replacement Take?
Most furnace replacements take one day; venting, a chimney liner, gas line or duct work can add a second. Ours run $4,500–$9,500 installed. Call 612-429-3465.

A furnace replacement in Mound runs $4,500–$9,500 installed, often a horizontal or compact model for a crawlspace or closet. We measure first, since the access hatch or closet door decides which furnace fits.
Replacing a furnace in a converted Mound cabin starts with the space. A closet furnace has to match the opening, the door clearance and the route its flue or PVC takes outside. A crawlspace unit is usually a horizontal model that has to fit through the access hatch and sit above any water. Condensing furnaces also need a drain route that won't freeze in a cold crawl. A crawlspace with sealed, insulated ducts suits a new furnace; one that can't be sealed makes ductless heat pumps the better investment.
On tight lake lots, a side-wall vent has to keep its clearances from windows, doors and the property line, which can decide where the furnace goes. Mound's postwar ramblers and split-levels are standard basement swaps. CenterPoint Energy supplies the gas, and its heating system rebates cover qualifying high-efficiency furnaces. Expect the city to require a mechanical permit for the swap.

By efficiency: 80% AFUE roughly $4,500–$6,000; 96–98% AFUE roughly $6,500–$9,500. See the furnace replacement cost guide.
Mound's gas comes from CenterPoint Energy and its electricity from Xcel Energy. CenterPoint's heating rebates cover high-efficiency gas furnaces, boilers and thermostats, installed by the dealer you choose. Ask us which rebates apply when we quote. Rebate programs change every year, so check the utility's current terms before you buy.

Often, but we measure before we price. Horizontal furnaces come in different cabinet widths and lengths, and some are compact enough to pass through a standard access opening. If the hatch is too small, it may need enlarging, which goes into the written quote. We also plan how the old furnace comes out and where the new condensate drain runs, so install day holds no surprises.
Sometimes, but it's rarely the simplest route. A wall furnace heats from one spot, and replacing it with a central furnace means adding ductwork, which is hard in a cabin with no basement and a shallow crawl. Ductless heat pumps usually fit these houses better: a head or two covers the main rooms, and they cool in summer too. With us, ductless systems run $4,200–$12,500 depending on the number of heads.
